check chmod.. with PHP

[sWo0p]

i already know how to change chmod but is there anyway to check chmod of a filename or dir.. ???

i don't think so.

however, you can change the permissions of a file using PHP. www.php.net/chmod

if your working on an application and require people to chmod, which is the situation i'm picturing, that's the best way to do it.

no im woriking on a check script that checks if the instalation has bin done correctly.. and some of my files need to be a chmod 777 and some need to be 644..
i want a listing that shows if the key files are correctly chmoded

that's what i assumed ;). what i meant was that you can use that to chmod it instead of having the user do it.

i can't think of a way to get a files permissions, i'll look out for it :)

If you have access to the PHP permissions, allow access to the console from your script (I think it's in your PHP.ini) and then just do a


`ls -l <yourFile>`


I've never done it before so I don't remember the syntax or how to enable it in PHP, but I am pretty sure it's possible to run commands via PHP.

If you only want to check that the file is writeable you can use


<?php
$filename = 'test.txt';
if (is_writable($filename)) {
echo 'The file is writable';
} else {
echo 'The file is not writable';
}
?>

If you only want to check that the file is writeable you can use


<?php
$filename = 'test.txt';
if (is_writable($filename)) {
echo 'The file is writable';
} else {
echo 'The file is not writable';
}
?> thats a good idea. Nice thought

EDIT: I found this code in the comments on the PHP chmod site:

When using ftp_rawlist, in order to get the chmod number from the attributes, i use this code:



function chmodnum($mode) {
$realmode = "";
$legal = array("","w","r","x","-");
$attarray = preg_split("//",$mode);
for($i=0;$i<count($attarray);$i++){
if($key = array_search($attarray[$i],$legal)){
$realmode .= $legal[$key];
}
}
$mode = str_pad($realmode,9,'-');
$trans = array('-'=>'0','r'=>'4','w'=>'2','x'=>'1');
$mode = strtr($mode,$trans);
$newmode = '';
$newmode .= $mode[0]+$mode[1]+$mode[2];
$newmode .= $mode[3]+$mode[4]+$mode[5];
$newmode .= $mode[6]+$mode[7]+$mode[8];
return $newmode;
}

well lets not go to deep in detail i just want to know if that file is writable.. so i think the if() script of sniper wil do perfectly.. but i'll keep both script in my collection.. you never know when it gets handy..
